Ideal for pull ups, muscle ups, levers and much more, the BLK BOX Free Standing Callisthenics Rig is the perfect home training solution for callisthenics.

Designed and manufactured in Belfast, the BLK BOX Callisthenics Rig is great to promote strength, endurance, flexibility, and coordination as well as augmenting the body's general well-being by placing controllable, regular demands upon the cardiovascular system.

Callisthenics is also great for maintaining better form as you will be working with your own bodyweight which will not only promote better technique but will also directly enhance the way you perform everyday life. Callisthenics involves using the entire body and not isolating or emphasizing certain muscles over others. You will build strength from the bottom of your feet to the tips of your fingers.

With the use of the BLK BOX Free Standing Callisthenics Rig you will be able to develop your fine motor skills that require your brain to work as hard as your body. As previously mentioned, callisthenics will enhance your coordination but will also enhance your speed, power, acceleration, agility and much more.

The BLK BOX Callisthenics Rig can be used for exercises that will function as physique builders or serve as warm-ups for more strenuous sports or exercises.


Made from start to finish in Belfast, the BLK BOX Free Standing Callisthenics Rig is manufactured from a range of locally sourced mild steel. Using our signature Goliath 60mm x 60mm x 3mm Box section, the rig stands at 2466mm tall and has a footprint of 2212mm x 1229.2mm. Our Callisthenics Rig has been created for those who want a heavy duty, high quality, locally manufactured product, fast. A pull up bar with a diameter of 33.7mm is also included with the rig.

Included with the BLK BOX Free Standing Callisthenics Rig is a pair of BLK BOX Human Flagpole Attachments. This attachment is the ultimate test of strength, stability, and balance. Combining shoulder strength with core stability, it is the ideal product for those with years of calisthenics experience to those who are just learning the range of movements.

The rig is coated with our signature black textured powdercoat finish. It will enter our internal industrial paint line, going through various stages of washing, drying, and painting before coming out freshly baked. Contact our team today for any queries on colours!

The textured powdercoat finish is not slippy and will allow for optimum grip throughout the duration of your workout. 

Optional extras include but are not limited to, a pair of BLK BOX Utility J-Hooks to transform this rig into a squat rack, BLK BOX Goliath Dip Station to strengthen your chest, shoulders, triceps and more. The BLK BOX Free Standing Callisthenics Rig is compatible with all Goliath Rig & Rack Attachments.
